为什么在循环控制之后，这个PHP for循环在没有分号的情况下执行？

Here is simple PHP code which executes without semicolon:

<?php
for($a=1; $a<=10;Print $a,$a++)
?>

How this is possible?

The closing tag of a block of PHP code automatically implies a semicolon; you do not need to have a semicolon terminating the last line of a PHP block.

See PHP Instruction separation.

As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement. The closing tag of a block of PHP code automatically implies a semicolon; you do not need to have a semicolon terminating the last line of a PHP block.
